Women
Obeying Islamic rules including Hijab or Islamic dress-code is necessary in Iran. However these rules are not observed very strict, especially for tourists and foreigners. You must not worry about maintaining your hijab , since in times you have forgotten about it, the maximum penalty will be a request (usually in a kind way) to make it correct. There are some minimum requirements for foreign women dress-code in public places:
- Color: It’s a completely false belief that wearing must be dark in Iran. There is no limitation in this respect and we recommend you make sure using light colors in summer.
- Head: Hair should be covered. It does not mean you shall have a tight scarf around your head. Don’t worry; it is very usual that some parts remain out of the cover. It’s quite acceptable for women to allow whips of their hair to frame their face. Appropriate hats & caps can do this function as well as scarves. Scarf is the most common covering for head and is called “Roosari” in Farsi.
- Body: Should be covered with loose clothes like man shirt, coat or manteau. Arms should not be bare.
- Legs & Feet: Legs should be covered down to ankles. Feet can be bare and you can wear sandals. Tight jeans are no problem.
